[SOLVED] Problems with Fedora kernels >= 4.18.17

zuzzurro

Hi everyone.
My Up² will not boot anymore using Fedora 29 kernels past 4.18.17. For the time being I'm forced to stay on 4.18.16. Issue seems starting mmcblk taking forever.

I discovered the reason for my trouble in booting. It looks like the root device minor number has changed from 0 to 1 for some reason.
Before:

mmc0: SDHCI controller on PCI [0000:00:1c.0] using ADMA 64-bit
mmc1: SDHCI controller on PCI [0000:00:1e.0] using ADMA 64-bit
mmc2: SDHCI controller on PCI [0000:00:1b.0] using ADMA 64-bit
mmc0: new HS400 MMC card at address 0001
mmcblk0: mmc0:0001 M52564 58.3 GiB

Now:
mmc0: SDHCI controller on PCI [0000:00:1b.0] using ADMA 64-bit
mmc1: SDHCI controller on PCI [0000:00:1c.0] using ADMA 64-bit
mmc2: SDHCI controller on PCI [0000:00:1e.0] using ADMA 64-bit
mmc1: new HS400 MMC card at address 0001
mmcblk1: mmc1:0001 M52564 58.3 GiB

I don't know why, but in any case all I had to do was to modify the fstab to cope with the new numbering, hoping it won't happen again.

Hi @zuzzurro ,

Thanks for the update about your problem.

Kernel 4.18 is not supported yet for UP, so for the future we would recommend you to use any supported software as Wiki says:

Thanks!

Hi, I was not complaining, it was just a heads up for other people to be careful. I know that if it break I get to keep both pieces.
All Fedora releases have been quite stable for me up to now, so no big deal. It's also good to know about the policy. Hopefully someone will be able to understand what broke precisely.
